Python script caused prime reboot - beta 2021-4-27

@tcab:
I'm not sure, but maybe it could be the special behavior of main.py within micropython.
Some filenames in micropython like main.py and boot.py have special meanings during startup.

If you could restore your backup to the Virtual Prime, try to remove or modify the main.py file.

Please have a look at https://forum.micropython.org/viewtopic.php?t=2504
("How to use main.py to deploy my code") and https://forum.micropython.org/viewtopic.php?t=5831

Edit: backup*.zip could be opened e.g. by 7-zip.
Your *.py files are located at subdir &Python.hpappdir\ and could be removed or renamed within 7-zip.
